The springs 16' are adapted to take up vibrations j infr travel on the road and also to absorb ations up when the current turned on momentarily when the curtain moves only a slight distance. vided at each end of the aligned solenoids to limit the upward and downwardmovement of the core when the curtain has been fully wound or unwound. he stop members are angular brackets one side being secured to the housing, the other side having a hole therein for the core and being spaced a short distance from the end of the solenoid coil. The springs 16 come in contact with the stop members'to arrest the movement of the core.

The device is mounted within a housing and secured to a. base plate 21 which may bel vsecured to theautomobile body by screws which are invisible from without. rl`he cover member may be arranged to stay in place by a force lit as shown in Figure 2. Y y

ln Figure 4 the schematic arrangement of the electrical circuits is shown. Each ot the solenoid coils 12, 13 is grounded at one end at 22 the other end being connected to a two circuit switch S. A source orp electricity is shown at B which may be the usual storage battery having one terminal grounded at 23, thepotherterminal being connected to switch S. It is apparent from the diagram that there are two independent circuits and that the two solenoids act independently ot each other. The core 14 is of sutlicient length to project into the second coil and by reason of the flux setup in the coil the core may be made to reciprocate. A slight tap on the s fitch will cause the core, and correspondingly the curtain to move a slight distance.V The switch should be placed near the driver and legends or characters such as D and'U may be used on the switch to indicate the direction of movement of the curtain.

A suitable fuse or thermostatic device F may be interposed in the circuit as shown in Figure 4 as a fool-proof means to prevent damageto the coils.

All that has been said above in the description of my preferred embodiment is olered by way of illustration and not limitation. l do not wish to be limited to the exact struc- .v of thelfollowing claims :A r

Stop members 20 are proequivalents which utilize the principle of my invention and 'allwithin the purview-of my invention and are within the spiritand scope V.The invention having been set forth what is claimed as new and useful is:

1. A remote curtain control device comprising a roller forthe curtain, Velectrical means external rof said curtain roller for rotating said curtain roller, said electrical means comprising two separately acting solenoid coils having a traveling coremeans therein, and means connecting said coremeans and said roller to impart rotation to said roller. A y i 2.,A remote curtain control device comprising a roller for the curtain, said` curtain roller being mounted for rotation, electrically actuated means adjacent one end o-said curtain roller and disposed thereto at substantially a right angle', said means being capable of rotating said curtainrollemsaid electrical means comprising two separately acting solenoid coils having aA traveling core means therein, and 'means 'connecting said Ycore meansV and said roller to impart rotation to said roller.

3. A device for shifting a curtain Jfor a dis- Y tance comprising a curtainroller mount-ed for rotation, an exterior electrically operated means at one end ofsaid curtain roller, pintle members on said curtain, one of said pintle members having a strand connected thereto, said strand being capable of movement by said electrically operated means whereby the curtain rollers is rotated, and a switch means for operating said electrically operated means. Y

4. A device for shifting a curtain or shade from a distance comprising a curtain roller mounted for rotation, an electromagnetic device adjacent one end of 'said curtain roller, a travellinP iron core within saidelectromagn-etic device, means connecting the ends of said travelling iron core with theend of said curtain roller,a source otcurrent, a switch conveniently positioned, whereby the closing of the circuit causes the ktravelling core to actuate the curtain roller.

5. A remote control device for winding and unwinding a curtain or shade comprising in combination" 'with one end of a rotatably mounted curtain roller, an electromagnetic device composed of two aligned separately acting solenoid coils, a common travelling core therein, means passing from the ends of said core to one end of said curtain roller, a source oi" current, a two circuitv switch conveniently positioned for energizing either lao coil whereby the curtain is wound or" un,-

wound. v

adjacent one end of said curtain roller, Ia

strand means v,connecting said core `Ywith oney y i end of said curtainroller, guidingfmeans therefor adapted' to delimit the travel of said core, and equalizing resilient means on said strand.
